In this talk, I will discuss the current status and prospects in inclusive semileptonic beauty and charm decays from the theoretical side. I will introduce the open-source package Kolya, developed to predict inclusive beauty semileptonic rates within the SM and beyond. I will discuss the status of the Vcb determinations from semileptonic inclusive B decays using all available data. I will...
The Heavy Quark Expansion (HQE) has become the major tool to perform precision calculations for inclusive heavy hadron decays. With this method, $V_{cb}$ has been extracted with percent-level precision from moments of $B\to X_c\ell\bar{\nu}$. The HQE is an expansion in $1/m_b$ and introduces nonperturbative HQE matrix elements which can be extracted from data.
To further increase the...
The present LHCb anomalies in the post-$R_K^*$ era are obscured by still unknown power corrections to these exclusive modes. The method of refactorization is an option to solve this problem in the long run. We present a successful example of the these new techniques in SCET within the power corrections to the inclusive $\bar B \to X_s \gamma$ decay. Another option is the crosscheck with...
The inclusive radiative decay mode $B \to X_s \gamma$ provides an important channel for new physics searches.
When the photon energy is large, $m_b - 2 E_\gamma \sim \mathcal{O}(\Lambda_{\rm QCD})$, methods from soft-collinear EFT can be used to construct a systematic heavy-quark expansion.
In this talk, I will discuss how to include $\mathcal{O}(\alpha_s)$ corrections to the...
The LHCb experiment has produced many intriguing results presenting tensions with respect to the Standard Model. These anomalies point towards potential contributions from New Physics. In particular, the anomalies observed in the decay $B^0 \rightarrow K^{*0} \mu^+ \mu^-$ motivate unbinned analyses in dimuon invariant mass squared ($q^2$), where more information about the decay can be...
ATLAS B-physics analysis exploit low and medium momenta leptons and hadrons, combined in trigger signatures, adapting with levels of instantaneous luminosity during LHC spills. The dedicated trigger strategies over Run2 and Run3 lead to collect data allowing high precision tests of HF phenomena, covering: rare decays, high precision measurements in CKM favoured B-hadron decays and HF...
Motivated by the remarkable Belle II experimental result on $B\to K ^{}\, E_{\rm miss}$, and phenomenological difficulties in accommodating it exclusively in terms of processes with SM neutrino final states, we systematically investigate possibilities that $E_{\rm miss}$ comes not only from the SM neutrinos but also from other light undetected particles. We consider both single scalar or...
In modern experiments on flavour physics it is possible to search for the decays of $B$’s, $D$’s, or $\tau$’s into final states with heavy neutrinos $N$ (a.k.a. heavy neutral leptons). I present a common study of theorists and experimentalists from Belle II on constraints on $B \rightarrow D^{*} \ell N$. Next I discuss the status of the theory predictions of the various $N$ decay rates. In...
